timeout cancels the old timeout. An example would be performing validation on a keypress.
You can use this class to buffer
the keypress events for a certain number of milliseconds, and perform only if they stop
for that amount of time.</div><div class="hr"></div><a id="Ext.util.DelayedTask-props"></a><h2>Public Properties</h2><div class="no-members">This class has no public properties.</div><a id="Ext.util.DelayedTask-methods"></a><h2>Public Methods</h2><table cellspacing="0" class="member-table"><tbody><tr><th colspan="2" class="sig-header">Method</th><th class="msource-header">Defined By</th></tr><tr class="method-row expandable"><td class="micon"><a href="#expand" class="exi">&nbsp;</a></td><td class="sig"><a id="Ext.util.DelayedTask-DelayedTask"></a><b><a href="source/DelayedTask.html#cls-Ext.util.DelayedTask">DelayedTask</a></b>(&nbsp;<span title="Optional" class="optional">[<code>Function&nbsp;fn</code>]</span>,&nbsp;<span title="Optional" class="optional">[<code>Object&nbsp;scope</code>]</span>,&nbsp;<span title="Optional" class="optional">[<code>Array&nbsp;args</code>]</span>&nbsp;)
